Abstract: Dihalocyclopropanation of the double bond of some olefins, leading to dihalocyclopropanes, offered an opportunity to perform their rearrangement to dihalomethylvinyl with Hiyama type reagents, in presence of cationic system such as Cr2+/Cr3+. The chain elongation of alkenes via the gem‐dihalocyclopropanes produced α,β‐unsaturated aldehydes and acids.
